Abstract
A channel (1) for the outflow/conditioning of molten glass includes a duct and superstructure (5) and is designed to transfer the molten glass from a vitrifiable material melting and refining zone (6) to a molten glass forming zone, in order to take it from its melting temperature to its forming temperature. It consists of a multiplicity of successive zones (8, 9, 10, 11, 12, 13, 14) located substantially transversely in relation to its longitudinal axis, each zone having its own function, being heat-controlled in an autonomous manner and insulated over part of its height relative to the adjacent zones by partitions (15). The zones include at least one transition zone (8), at least one drainage zone (9), at least cooling zone (10, 11, 12) and at least one thermal and/or chemical homogenization zone (13, 14).
